    Valve operations during an emergency... Emergency shut-off valve (release valve)

    These are Automatic valves run on electricity.
    If there’s a power outage and they stop working, you will have problems...

    Use Emergency (Shut-off/Release) Valve Electric Actuated Type E.

    When the power source is lost, the spring forcibly operates the valve to ensure that it is fully opened or closed, preventing secondary damage such as a chemical leak, fire or explosion.

    Actuator replacement... Pneumatic Actuated Ball Valve Type AR

    Many of our customers have commented on how fiddly it is to disassemble and assemble the bolts and couplings that connect actuators with valves when they replace the actuator in an existing valve!

    Use our Pneumatic Actuated Ball Valve Type AR.

    We have eliminated the fiddly work by designing the mount that connects the actuator to the valve with a snap-in construction. Known as one-touch connection

    You can also use different colors to make the piping easily identifiable.

    • Plastic actuator resists corrosion and rust
    • Much lighter than metal models, and more compact with its own mount
    • Easy maintenance with the snap-in actuator
  • Draining off fluid when replacing a valve... Butterfly Valve Type 57L

    Draining off fluid when replacing a valve... Butterfly Valve Type 57L

    When replacing a standard butterfly valve, you need to drain off any fluid in the pipe. Many of our customers have commented on how fiddly that is.

    Use our Butterfly Valve Type 57L.

    There is no need to drain off the fluid since the pipe on the secondary side can be removed while the fluid is stopped by the valve.

Leakage

  • Preventing chemical leakage from pipes... AV Double Contained Pipe

    Preventing chemical leakage from pipes... AV Double Contained Pipe

    Factory pipes are often used for chemicals such as hydrofluoric acid that would be dangerous if they came into contact with the human body.
    When such dangerous chemicals are carried through pipes laid above passageways or ceilings, there is a risk of workplace injuries or fatalities if a pipe should leak.
    There is also a risk of damage to apparatus if the fluid becomes dispersed into the equipment.

    The Water Pollution Control Law makes appropriate management of equipment mandatory in order to prevent the contamination of groundwater by chemicals that contain toxic substances.
    The leakage of chemicals from pipes must be prevented to protect the environment as well.

    The dual structure of the pipe means that, even if there should be a leak, the fluid is prevented from spraying or leaking outside of the pipe.
    Visual inspections are easy if the outer pipe is made transparent.
    We can also manufacture transparent boxes to prevent spray from flanges and valves.

    • The dual construction of an inner and outer pipe prevents the dispersal of chemicals
    • It is easy to check for leaks if transparent vinyl chloride is used for the outer pipe
    • Can handle expansion and contraction thanks to the separation of the inner and outer pipes

    AV pipes and drain pans are also effective measures against chemical leaks.

  • Pipe installation with a lower risk of leaks… Prefabricated AV pipe

    Pipe installation with a lower risk of leaks… Prefabricated AV pipe

    In recent years there has been a generational shift in the construction industry combined with a lack of workers. As a result, we are seeing many cases of bad workmanship by people who do not yet have sufficient technical experience.
    Installation work involving AV pipes in particular requires specialized knowledge and techniques, which means that leakage problems can easily occur as a result of bad workmanship.

    Consider using prefabricated AV pipe plumbing.

    Send us data such as drawings and isometric drawings, and we will do a study and manufacture piping that can reduce on-site installation work.
    We can offer PP piping as well as AV pipes.

    • Lower costs thanks to reduced on-site installation work, shorter delivery times
    • We can manufacture shapes that cannot be produced by joining molded items
    • Safe and reliable prefabricated items guaranteed by the manufacturer

On-site Installation

  • Limited plumbing space... Short face-to-face joints, AV minimum joints

    Limited plumbing space... Short face-to-face joints, AV minimum joints

    Work using elbow joints or T-joints inevitably requires a lot of space.
    Sometimes it is impossible to secure a large space in the plumbing, for example in the area around a machine.

    Use our short face-to-face joints or AV minimum joints.

    • av_minimum_joints

    We cut and standardize joints to the absolute minimum length required to guarantee the adhesive bonding strength of the joint and the pipe.
    This minimizes the space required and makes it possible to install plumbing in confined spaces.

    • Save space with short face-to-face joints for PVC pipes and minimum joints for AV pipes
    • Flange connection makes on-site installation work easy (AV minimum joints)
    • Sufficient adhesive strength is a given!
  • Analysis of piping curvature... Our piping stress analysis service

    Analysis of piping curvature... Our piping stress analysis service

    Plastic pipes expand and contract with the heat. Without appropriate support, curvature and warping can sometimes occur due to temperature fluctuations caused by operating conditions and seasonal changes.
    There is a risk that inappropriate support will generate concentrated stress in the pipes, leading to leaks and damage.

    Use our piping stress analysis service.

    If you provide us with the drawings and operating conditions, we will pinpoint the spots where concentrated stress is likely to occur.

    • Pinpoints spots vulnerable to concentrated stress from the drawings and operating conditions
    • Analysis takes into account the surrounding environment and operating conditions
    • After the analysis, separate design and installation solutions are also available

    In addition, we can respond to your needs with the most appropriate design and installation solutions, based on the know-how we have built up during our many years of engineering experience. For example, we can offer designs that incorporate measures to deal with expansion/installation at elbow joints, and cushion saddles.

  • Pipe expansion and contraction due to temperature differences

    It is possible to calculate the amount of temperature-induced expansion and contraction in plastic pipes from the linear expansion coefficient of the plastic, the temperature difference, and the spacing of the supports.
    Please use the handy calculator below.

    Handy calculator for pipe expansion and contraction due to temperature differences

    ΔL = α × Δt × L
